Abstract (en)

[origin: WO2019217786A1] A user equipment that communicates over a radio interface with a base station apparatus of a radio access network (RAN) comprises processor circuitry and receiver circuitry. The processor circuitry is configured to initiate a first type system information block (SIB) acquisition process to receive a first type SIB. The first type SIB comprises scheduling information of a second type SI message, the second type SI message comprising at least one system information block (SIB); and an indication of broadcast status for the second type SI message, the indication indicating broadcasting. The receiver circuitry is configured to receive the first type SIB. The processor circuitry is further configured to initiate an SI message acquisition process to receive the SI message. In a case that a stored version of one of the at least one second type SIB is not valid, the first type SIB acquisition process is initiated upon a failure of the SI message acquisition process.
